Description

Technical Field

[0001] The present invention relates to the technical field of pearl - shaped detergent production equipment, and in particular to a vibrating granule - counting machine. Background Art

[0002] At present, the automatic packaging production line of pearl - shaped detergents mainly uses a combination scale for counting, and the combination scale counts by weighing. Due to the deviation in the gram weight of the pearl - shaped detergents themselves, when the number of products to be packaged is large, the error rate of counting by the combination scale will increase. As a result, it is necessary to detect the total weight of the packaged products in all subsequent processes and manually add or remove pearl - shaped detergents according to the size of the total weight, which greatly increases the labor cost. Summary of the Invention

[0003] An object of the present invention is to provide a vibrating granule - counting machine, aiming to solve the technical problem of high error rate in counting of the existing vibrating granule - counting machine.

[0004] The present application provides a vibrating granule - counting machine, which includes a feeding mechanism and a granule - counting mechanism. The feeding mechanism is used for conveying pearl - shaped detergents. The granule - counting mechanism includes a blanking box and a photoelectric counter located outside the blanking box. The blanking box is located below one side of the feeding mechanism. The blanking box has a blanking channel extending in the vertical direction. The upper end of the blanking channel is open to form a blanking inlet. The blanking channel receives the pearl - shaped detergents coming from the feeding mechanism through the blanking inlet. The blanking box is provided with a first through - hole communicating with the blanking channel, and the photoelectric counter counts the pearl - shaped detergents falling into the blanking channel through the first through - hole.

[0005] In one embodiment, the feeding mechanism includes a first driving unit, a first feeding unit and a second feeding unit all for conveying pearl - shaped detergents. The second feeding unit has at least two material - dividing channels for the pearl - shaped detergents to pass through. The first feeding unit, the second feeding unit and the blanking box are arranged in sequence along the horizontal direction. One end of the first feeding unit close to the blanking box is located above all the material - dividing channels and covers one end of all the material - dividing channels far from the blanking box. One end of the second feeding unit close to the blanking box is located above the blanking inlet and covers one end of the blanking inlet close to the second feeding unit. The first driving unit is drivingly connected to the first feeding unit and the second feeding unit to vibrate the first feeding unit and the second feeding unit.

[0006] In one embodiment, the first driving unit includes a driving assembly, an eccentric wheel, a first eccentric connecting rod and a second eccentric connecting rod. One end of the first eccentric connecting rod and the second eccentric connecting rod is rotatably sleeved on the outer surface of the eccentric wheel. The other ends of the first eccentric connecting rod and the second eccentric connecting rod are respectively hinged to the first feeding unit and the second feeding unit. The driving assembly is drivingly connected to the eccentric wheel to rotate the eccentric wheel, thereby driving the first eccentric connecting rod and the second eccentric connecting rod, and further vibrating the first feeding unit and the second feeding unit.

[0007] In one embodiment, the second feeding unit includes a vibrating screen, a second swinging assembly, and a second connecting rod. The second swinging assembly is rotatably connected to a support frame. The second connecting rod is hinged to the upper end of the second swinging assembly. The vibrating screen is connected to the second connecting rod. The vibrating screen is provided with a material distribution channel. The first driving unit is drivingly connected to the lower end of the second swinging assembly to swing the second swinging assembly.

[0008] In one embodiment, the driving assembly includes a driving motor, a driving wheel, a driven wheel, and a belt. The driving wheel and the driven wheel are both rotatably connected to an external object. The belt is movably sleeved on the outer surfaces of the driving wheel and the driven wheel to form a belt transmission structure. The driven wheel is connected to the eccentric wheel. The driving motor is drivingly connected to the driving wheel to rotate the driving wheel.

[0009] In one embodiment, the driving assembly is a driving motor. The driving motor is drivingly connected to the eccentric wheel to rotate the eccentric wheel.

[0010] In one embodiment, the counting mechanism further includes at least one switch door unit located below the first through hole. The switch door unit includes a baffle, a driving source, and a mounting plate. The driving source is mounted on the mounting plate. The driving source is drivingly connected to the baffle to make the baffle perform a reciprocating linear motion. The baffle is used to close or open the blanking channel.

[0011] In one embodiment, the switch door unit further includes a guide post and a guide sleeve mounted on the mounting plate. The guide sleeve is sleeved on the outer surface of the guide post and is slidably connected to the guide post. One end of the guide post close to the blanking channel is connected to the baffle. The driving source is drivingly connected to the end of the guide post away from the blanking channel.

[0012] In one embodiment, the switch door unit further includes a connecting member. The driving source is drivingly connected to the connecting member. An insertion hole for inserting the guide post is formed in the end face of the connecting member close to the blanking channel. The connecting member is further provided with a clamping groove communicated with the insertion hole. A clamping member is provided at one end of the guide post away from the baffle. The clamping member is configured to be detachably clamped in the clamping groove.

[0013] In one embodiment, the switch door unit further includes a guide wheel. The guide wheel is rotatably connected to the mounting plate and is used for rolling friction with the surface of the baffle.

[0014] In one embodiment, the clamping groove includes a first section, a second section, and a third section for limiting and abutting against the connecting member, which are connected in sequence. The first section extends along the axial direction of the insertion hole and penetrates the surface of the connecting member close to the blanking channel. The second section extends along the circumferential direction of the insertion hole. The third section extends in the direction close to the blanking channel at the second section. An elastic member for elastically abutting against the guide post is connected to the wall surface of the insertion hole away from the blanking channel. The baffle is rotatably clamped on the guide post.

[0015] In one embodiment, a convenient structure is provided at one end of the guide post close to the blanking channel. The convenient structure is used for being driven by a staff member so that the guide post is disengaged from or fixed to the connecting member.

[0016] The beneficial effects of the vibrating granulating machine provided by the present invention are as follows: The feeding mechanism transports the condensate beads to the granulating mechanism. The condensate beads fall along the extending direction of the blanking channel by their own gravity. When the condensate beads pass through the photoelectric counter during the falling process, the photoelectric counter detects the condensate beads and counts them. Compared with the traditional vibrating granulating machine that uses a combination scale for counting, this vibrating granulating machine uses a photoelectric counter to count the condensate beads falling into the blanking channel in the way of photoelectric detection and counting, and will not cause counting errors due to the weight deviation of the condensate beads themselves. In addition, since this vibrating granulating machine uses a photoelectric counter instead of a combination scale, the risk of the condensate beads being clamped and damaged can be reduced, and the cleaning time required for the vibrating granulating machine due to the condensate beads being clamped and damaged can be reduced.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0060] Now, the vibrating granule counting machine 100 in the embodiments of the present invention will be described.

[0061] For the convenience of description and understanding, please refer to Figure 1 , and define the front-rear direction, left-right direction, and up-down direction.

[0062] Please refer to Figure 1 and Figure 2 , the vibrating granule counting machine 100 provided in the present application includes a feeding mechanism 10 and a granule counting mechanism 20. The feeding mechanism 10 is used for conveying the condensate beads. The granule counting mechanism 20 includes a blanking box 21 and a photoelectric counter 23 located outside the blanking box 21. The blanking box 21 is located below one side of the feeding mechanism 10. The blanking box 21 has a blanking channel 211 extending in the up-down direction. The upper end of the blanking channel 211 is open to form a blanking inlet 214. The blanking channel 211 receives the condensate beads coming from the feeding mechanism 10 through the blanking inlet 214. The blanking box 21 is provided with a first through hole 212 communicating with the blanking channel 211. The photoelectric counter 23 counts the condensate beads falling into the blanking channel 211 through the first through hole 212.

[0063] In the vibrating granulator 100 provided in this application, the first through hole 212 is opened on the rear end surface of the blanking box 21. The photoelectric counter 23 is located at the rear side of the blanking box 21. The feeding mechanism 10 conveys the condensate beads to the granulating mechanism 20. The condensate beads fall along the extension direction of the blanking channel 211 by their own gravity. When the condensate beads pass through the photoelectric counter 23 during the falling process, the photoelectric counter 23 detects the condensate beads and counts them. Compared with the traditional vibrating granulator 100 that uses a combination scale for counting, this vibrating granulator 100 adopts a photoelectric counter 23 to count the condensate beads falling into the blanking channel 211 in the way of photoelectric detection counting, and will not cause counting errors due to the weight deviation of the condensate beads themselves. In addition, since this vibrating granulator 100 uses a photoelectric counter 23 instead of a combination scale, the risk of the condensate beads being clamped and damaged can be reduced, and the cleaning time required for the vibrating granulator 100 due to the clamped and damaged condensate beads can be reduced. The photoelectric counter 23 is arranged outside the blanking box, which can avoid the mutual collision between the condensate beads and the photoelectric counter 23, thereby reducing the damage of the photoelectric counter 23 and the condensate beads.

[0064] It can be understood that the photoelectric counter 23 can be installed on the blanking box 21 or on the surface of other external objects, as long as the photoelectric counter 23 can be fixed, which is not limited here. The blanking channel 211 has a blanking outlet with an opening facing downwards and used for the condensate beads to leave the blanking channel 211.

[0065] In some embodiments, please refer to Figure 1 and Figure 3 , the feeding mechanism 10 includes a first driving unit 11, a first feeding unit 13 and a second feeding unit 12 that are all used for conveying the condensate beads. The first feeding unit 13, the second feeding unit 12 and the blanking box 21 are arranged at intervals in a predetermined direction in sequence. The second feeding unit 12 has at least two material distribution channels 1231 for the condensate beads to pass through. The first driving unit 11 is drivingly connected to the first feeding unit 13 and the second feeding unit 12 to vibrate the first feeding unit 13 and the second feeding unit 12.

[0066] In this embodiment, the first feeding unit 13, the second feeding unit 12 and the blanking box 21 are arranged in sequence in the front-rear direction. The front end of the first feeding unit is located above all the material distribution channels and covers the rear ends of all the material distribution channels. The front end of the second feeding unit is located above the blanking inlet and covers the rear end of the blanking inlet. Such a setting is to ensure that the condensate beads can fall from the storage tray onto each material distribution channel and then fall from each material distribution channel to the blanking inlet. The material distribution channels 1231 extend in the front-rear direction, and more than two material distribution channels 1231 are arranged at intervals in the left-right direction. By setting the material distribution channels 1231, the stacked condensate beads are separated, which is beneficial to reducing the stacking between the condensate beads, thereby further improving the counting accuracy.

[0067] When the vibration granulator 100 is working, a plurality of condensate beads located on the first feeding unit 13 fall into different material distribution channels 1231 respectively under the action of vibration, and gradually approach the blanking box 21 under the action of vibration as well, and finally fall into the blanking channel 211.

[0068] In some embodiments, the number of the blanking channels 211, the number of the photoelectric counters 23 and the number of the material distribution channels 1231 are equal. A plurality of blanking channels 211 and a plurality of material distribution channels 1231 correspond to each other one by one respectively, and a plurality of photoelectric counters 23 and a plurality of blanking channels 211 correspond to each other one by one respectively. Each blanking channel 211 has a first through hole 212. With such a setting, the condensate beads in a certain material distribution channel 1231 can only fall into the blanking channel 211 corresponding to the material distribution channel 1231, greatly improving the counting accuracy. Of course, the number of the material distribution channels 1231 can be two, three, four, five, six, etc., or even more. The number of the material distribution channels 1231 needs to be determined according to the actual situation and is not limited herein.

[0069] In some embodiments, please refer to Figure 1 and Figure 4 , the first driving unit 11 includes a driving assembly, an eccentric wheel 111, a first eccentric connecting rod 112 and a second eccentric connecting rod 113. One ends of the first eccentric connecting rod 112 and the second eccentric connecting rod 113 are rotatably sleeved on the outer surface of the eccentric wheel 111. The other ends of the first eccentric connecting rod 112 and the second eccentric connecting rod 113 are respectively hinged to the first feeding unit 13 and the second feeding unit 12. The driving assembly is drivingly connected to the eccentric wheel 111 to make the eccentric wheel 111 rotate, thereby driving the first eccentric connecting rod 112 and the second eccentric connecting rod 113, and further making the first feeding unit 13 and the second feeding unit 12 vibrate.

[0070] Understandably, the number of the first eccentric connecting rods 112 and the number of the second eccentric connecting rods 113 can be one or more than two. The number of the first eccentric connecting rods 112 and the number of the second eccentric connecting rods 113 can be the same or different, as long as the first feeding unit 13 and the second feeding unit 12 can be driven under the drive of the driving assembly, which is not limited herein. In this embodiment, the number of both the first eccentric connecting rod 112 and the second eccentric connecting rod 113 is one. The eccentric wheel 111 includes an eccentric shaft 1111 and a circular wheel 1112. The eccentric shaft 1111 is eccentrically arranged on the end face of the circular wheel 1112. One ends of the first eccentric connecting rod 112 and the second eccentric connecting rod 113 are rotatably sleeved on the outer surface of the circular wheel 1112, and the driving assembly is drivingly connected to the eccentric shaft 1111. During operation, the driving assembly drives the eccentric shaft 1111 to rotate the eccentric shaft 1111 around its axis, thereby driving the circular wheel 1112 to rotate around the axis of the eccentric shaft 1111, and further driving the first eccentric connecting rod 112 and the second eccentric connecting rod 113. The first feeding unit 13 and the second feeding unit 12 swing back and forth respectively under the drive of the first eccentric connecting rod 112 and the second eccentric connecting rod 113, thereby generating vibration.

[0071] It can be seen that in the above embodiment, mechanical vibration is adopted, that is, vibration is realized by adopting mechanical structures such as eccentric structures and connecting rod structures. Compared with traditional electromagnetic vibration, mechanical vibration has a larger vibration amplitude. In addition, the vibrating granulator 100 provided in the present application is used for the production of laundry beads, and the laundry beads themselves have a certain absorption and weakening effect on vibration. The amplitude and accessories of the traditional vibrating disk are not applicable and cannot effectively transport. In addition, by using one driving assembly to simultaneously drive the first eccentric connecting rod 112 and the second eccentric connecting rod 113, so that the first feeding unit 13 and the second feeding unit 12 vibrate. On the one hand, the production cost can be reduced and resources can be saved; on the other hand, when the driving assembly fails, both the first feeding unit 13 and the second feeding unit 12 will stop vibrating at the same time. Compared with using two driving energy sources to respectively drive the first eccentric connecting rod 112 and the second connecting rod, this design can avoid the situation where the first feeding unit 13 vibrates while the second feeding unit 12 does not move, and the laundry beads are stacked on the second feeding unit 12.

[0072] In some embodiments, please refer to Figure 3 , the second feeding unit 12 includes a vibrating screen 123, a second swinging assembly 121 and a second connecting rod 122. The second swinging assembly 121 is rotatably connected to a support frame 14. The second connecting rod 122 is hinged to the upper end of the second swinging assembly 121. The vibrating screen 123 is connected to the second connecting rod 122. The vibrating screen 123 is provided with a material distribution channel 1231. The first driving unit 11 is drivingly connected to the lower end of the second swinging assembly 121 to swing the second swinging assembly 121.

[0073] Specifically, the second swing assembly 121 includes a third connection part 1211 and two second support modules. The two second support modules are arranged at intervals in the front-rear direction. Each of the two second support modules includes a second mandrel 1212 and a fourth connection part 1213. The second mandrel 1212 passes through the upper end of the third connection part 1211 and is fixedly connected to the third connection part 1211. A fourth connection part 1213 is fixedly connected to each of the left and right ends of the second mandrel 1212. Both of the two second mandrels 1212 are rotatably connected to the support frame 14. The two fourth connection parts 1213 on the left side are hinged to a second connecting rod 122, and the two fourth connection parts 1213 on the right side are hinged to a second connecting rod 122. The left and right ends of the vibrating screen 123 are respectively connected to the two second connecting rods 122. The front end of the second eccentric connecting rod 113 is hinged to the third connection part 1211 at the rearmost side. This structure is relatively simple and has a low assembly difficulty, which is beneficial to reducing the production cost. Of course, the second eccentric connecting rod 113 can also be hinged to another third connection part 1211, as long as the second eccentric connecting rod 113 can drive the third connection part 1211 to swing back and forth, which is not limited herein. In some other embodiments, the number of the second support modules can be three or even more, and the number of the second support modules is not limited herein.

[0074] During operation, the second eccentric connecting rod 113 drives the third connection part 1211 to swing back and forth, causing the fourth connection part 1213 to also swing back and forth, thereby driving the second connecting rod 122 and the vibrating screen 123 to translate back and forth along an arc-shaped trajectory, and further causing the vibrating screen 123 to vibrate, realizing the conveying of the condensate beads.

[0075] In some embodiments, please refer to Figure 1 and Figure 3 , a corrugated surface 1232 is provided on the upper surface of the vibrating screen 123. The corrugated surface 1232 undulates in the left-right direction and extends in the front-rear direction. The corrugated surface 1232 defines a material distribution channel 1231. In addition, the left and right ends of the corrugated surface 1232 can also be connected to the left and right inner wall surfaces of the vibrating screen to define the material distribution channel 1231. The corrugated surface 1232 is connected by a plurality of inclined planes. Of course, in some other embodiments, the corrugated surface 1232 can be connected by a plurality of arc surfaces. By providing the corrugated surface 1232, the stacked condensate beads coming from the first feeding unit 13 can be dispersed and roughly evenly distributed into each material distribution channel 1231, reducing the stacking between the condensate beads, which is beneficial to improving the accuracy of counting.

[0076] Optionally, there are two or more corrugated surfaces 1232, and they are arranged in a stepped shape with each layer descending in the direction close to the blanking box 21. With this arrangement, the distance between the condensate beads in each material distribution channel 1231 can be increased, avoiding the stacking of condensate beads, which is beneficial to improving the accuracy of counting.

[0077] In some embodiments, please refer to Figure 1 and Figure 3 , the upper surface of the vibrating screen 123 is further provided with a plurality of discharge channels 1233 extending in the front-rear direction. Each discharge channel 1233 is located on the front side of the material distribution channel 1231. Each discharge channel 1233 is connected to the material distribution channel 1231. The bottom wall surface of each discharge channel 1233 is a flat surface. The condensate beads in the material distribution channel 1231 enter the discharge channel 1233 under the action of vibration and finally fall into the blanking channel 211 from the discharge channel 1233. By providing the discharge channels 1233, a plurality of condensate beads are arranged in sequence in the front-rear direction.

[0078] In some embodiments, please refer to Figure 3 , waist-shaped holes 1234 are provided on both the left and right sides of the vibrating screen 123. Two support members 1221 are provided on the two opposite surfaces of the two second connecting rods 122. The four waist-shaped holes 1234 and the four support members 1221 correspond to each other one by one. The support member 1221 is slidably adapted to the corresponding waist-shaped hole 1234, and the support member 1221 is used to support the vibrating screen 123. With this setting, fast disassembly of the vibrating screen 123 can be achieved without using fasteners such as screws and bolts.

[0079] In some embodiments, please refer to Figure 1 , the first feeding unit 13 includes a storage tray 131, a first swinging assembly, and a first connecting rod. The first swinging assembly is rotatably connected to the support frame 14. The first connecting rod is hinged to the upper end of the first swinging assembly. The storage tray 131 is connected to the first connecting rod. The first driving unit 11 is drivingly connected to the lower end of the first swinging assembly to swing the first swinging assembly.

[0080] Specifically, the storage tray 131 is used to store a large number of beads. The beads enter the vibrating sieve 123 from the storage tray 131 under the action of vibration. The first swinging assembly includes a first connecting portion and two first supporting modules. The two first supporting modules are arranged at intervals in the front-rear direction. Each of the two first supporting modules includes a first core shaft and a second connecting portion. The first core shaft penetrates through the upper end of the first connecting portion and is fixedly connected to the first connecting portion. A second connecting portion is fixedly connected to each of the left and right ends of the first core shaft. Both of the two first core shafts are rotatably connected to the support frame 14. The two second connecting portions on the left side are hinged to a first connecting rod, and the two second connecting portions on the right side are hinged to a second connecting rod 122. The left and right ends of the storage tray 131 are respectively connected to the two first connecting rods. The rear end of the first eccentric connecting rod 112 is hinged to the first connecting portion at the forefront. Of course, the first eccentric connecting rod 112 can also be hinged to another first connecting portion, as long as the first eccentric connecting rod 112 can drive the first connecting portion to swing back and forth, and this is not limited herein. In some other embodiments, three or even more first supporting modules can be provided, and the number of the first supporting modules is not limited herein. The working principle of the first feeding unit 13 is the same as that of the second feeding unit 12, and will not be elaborated herein.

[0081] Optionally, the assembly manner of the storage tray 131 and the first connecting rod is the same as that of the vibrating sieve 123 and the second connecting rod 122, and will not be elaborated herein.

[0082] It should be noted that the structure of the first connecting portion and the structure of the third connecting portion 1211 may be the same or different. Similarly, the structure of the first supporting module and the structure of the second supporting module may be the same or different, as long as they can drive the storage tray 131 and the vibrating sieve 123 to vibrate under the drive of the first driving unit 11, and this is not limited herein.

[0083] It can be understood that by adjusting the lengths of the first connecting portion and the third connecting portion 1211, the vibration amplitudes of the vibrating sieve 123 and the storage tray 131 can be changed, thereby changing the conveying speed of the beads.

[0084] In some embodiments, the driving assembly is a driving motor 114, and the driving motor 114 is drivingly connected to the eccentric wheel 111 to make it rotate. Specifically, the driving motor 114 is a variable-frequency motor. The output shaft of the driving motor 114 is connected to the eccentric shaft 1111 to make the eccentric shaft 1111 rotate. By using a variable-frequency motor to drive the eccentric shaft 1111, the rotation speed of the eccentric wheel 111 is adjusted by adjusting the variable-frequency motor, so as to achieve the purpose of changing the vibration frequencies of the storage tray 131 and the vibrating sieve 123.

[0085] In some embodiments, please refer to Figure 1 and Figure 4, the driving assembly includes a driving motor 114, a driving wheel 115, a driven wheel 116 and a belt 117. The driving wheel 115 and the driven wheel 116 are both rotatably connected to an external object. The belt 117 is movably sleeved on the outer surfaces of the driving wheel 115 and the driven wheel 116 to form a belt 117 transmission structure. The driven wheel 116 is connected to the eccentric wheel 111, and the driving motor 114 is drivingly connected to the driving wheel 115 to make it rotate. In this embodiment, the driving motor 114 is also a variable-frequency motor. The driving motor 114 drives the driving wheel 115 to rotate. Under the action of the belt 117, the driven wheel 116 also rotates, thereby driving the eccentric wheel 111 to rotate. If the driving motor 114 is directly used to drive the eccentric wheel 111, when other mechanical structures such as the first eccentric connecting rod 112, the second eccentric connecting rod 113, the first swing assembly, and the second swing assembly 121 are jammed or malfunction, it is easy to cause the driving motor 114 to be overloaded. If a combined structure of the driving motor 114 and the belt 117 transmission structure is adopted, when the above problems occur, the belt 117 can achieve a buffering effect through its own slipping, reducing mechanical damage to other mechanical structures such as the driving motor 114, the first eccentric connecting rod 112, and the first swing assembly. While improving the service life of this vibrating grain counting machine 100, the maintenance cost is reduced.

[0086] In some embodiments, please refer to Figure 1 and Figure 2 , the grain counting mechanism 20 further includes at least one switch door unit 22 located below the first through hole 212. The switch door unit 22 includes a baffle 224, a driving source 225 and a mounting plate 226. The driving source 225 is installed on the mounting plate 226. The driving source 225 is drivingly connected to the baffle 224 to make the baffle 224 perform a reciprocating linear motion. The baffle 224 is used to close or open the blanking channel 211.

[0087] The number of the blanking channels 211 is the same as the number of the discharge channels 1233, and they correspond to each other one by one. The blanking box 21 further has a converging channel 213. The converging channel 213 is located below the blanking channels 211. Each blanking channel 211 communicates with the converging channel 213 through its own blanking outlet. The condensate beads converge in the converging channel 213 after coming out of each blanking channel 211 and flow out of the blanking box 21 from the converging channel 213 to perform the next process.

[0088] In this embodiment, taking the number of blanking channels 211 as four as an example, there are four switch door units 22, and the four switch door units 22 correspond to the four blanking channels 211 one by one. The mounting plate 226 is located at the rear side of the blanking box 21, and a through hole for the baffle 224 to pass through is formed in the rear end surface of the blanking box 21. By setting the switch door unit 22, the opening and closing of the blanking channel 211 are controlled, so that the working states of each blanking channel 211 are relatively independent. That is, when one blanking channel 211 is in the open state, another blanking channel 211 can be in the open state or in the closed state. Each photoelectric counter 23 is preset with a preset value, and the sum of the preset values of all the photoelectric counters 23 is the total number of condensate beads leaving the blanking box 21 from the converging channel 213. When the number of condensate beads passing through the blanking channel 211 reaches the preset value of the photoelectric counter 23 corresponding to the blanking channel 211, the driving source 225 corresponding to the blanking channel 211 will drive the baffle 224 to move forward to close the blanking channel 211. At this time, there will still be condensate beads falling into the blanking channel 211 and dropping onto the baffle 224 until all the photoelectric counters 23 reach their preset values, and then the baffle 224 will move backward under the drive of the driving source 225 to open the blanking channel 211. It can be understood that the sum of all the photoelectric counters 23 is determined according to actual needs, and the preset value of each photoelectric counter 23 can be set arbitrarily.

[0089] Optionally, please refer to Figure 2 , at least two switch door units 22 are correspondingly arranged for each blanking channel 211, and the at least two switch door units 22 are arranged at intervals along the extending direction of the corresponding blanking channel 211. When the baffle 224 extends out to close the blanking channel 211, the condensate beads fall on the upper surface of the baffle 224 and stack up, and a space for storing a plurality of condensate beads is formed by the enclosure of the baffle 224 and the wall surface of the blanking channel 211. When all the photoelectric counters 23 reach the preset values, the baffle 224 retracts to open the blanking channel 211, so that the condensate beads stacked on the baffle 224 fall into the converging channel 213. With such a setting, the waiting time for the next process can be reduced, and the work efficiency can be improved. For each additional switch door unit 22, it is equivalent to having an additional storage space, further improving the work efficiency.

[0090] It can be understood that the driving source 225 can be a cylinder, an electric cylinder, or a matching structure of a motor and a rack and pinion, as long as it can realize the reciprocating linear motion of the baffle 224, and it is not limited here. In this embodiment, the driving source 225 is a cylinder, which is cheap and has a low assembly difficulty.

[0091] In some embodiments, please refer to Figure 1 、 Figures 10 to 12, on the rear wall surface of each blanking channel 211, there are two groups of first through holes 212 arranged at intervals in the up and down directions. Each blanking channel 211 corresponds to two photoelectric counters 23, and these two photoelectric counters 23 respectively correspond to the two first through holes 212 on each blanking channel 211. Below the blanking box 21, there is a hopper 30. The hopper 30 is provided with a cavity, a strong discharge channel 32, and a discharge channel 31. The opening of the cavity faces upward, and both the strong discharge channel 32 and the discharge channel 31 communicate with the cavity. On one side of the hopper 30, there is a second driving unit 40 and a third driving unit 50. The second driving unit 40 and the third driving unit 50 are respectively drivingly connected with a discharge blocking block 60 and a strong discharge blocking block 70, and both the discharge blocking block 60 and the strong discharge blocking block 70 are located in the cavity. The discharge blocking block 60 rotates above the discharge channel 31 under the drive of the second driving unit 40 to achieve the purpose of opening or covering the discharge channel 31. Similarly, the strong discharge blocking block 70 rotates above the strong discharge channel 32 under the drive of the third driving unit 50 to achieve the purpose of opening or covering the strong discharge channel 32.

[0092] During the actual production process, if only one photoelectric counter 23 is used to count the beads in a blanking channel 211, it is possible that the total number of required beads is incorrect due to misoperation of the photoelectric counter 23. In this embodiment, two photoelectric counters 23 are used to count the beads in a blanking channel 211. When the values of the two photoelectric counters 23 used to calculate the number of beads in the same blanking channel 211 are the same, the strong discharge blocking block 70 covers the strong discharge channel 32 to prevent the beads from entering the strong discharge channel 32, and the discharge blocking block 60 is located at a preset position to expose the discharge channel 31, so that the beads falling out of the blanking box 21 can fall into the discharge channel 31 and enter the next process through this discharge channel 31. When the values of the two photoelectric counters 23 used to calculate the number of beads in the same blanking channel 211 are inconsistent, it means that at least one photoelectric counter 23 has misoperated. At this time, the second driving unit 40 drives the discharge blocking block 60 to rotate to cover the discharge channel 31, while the third driving unit 50 drives the strong discharge blocking block 70 to rotate to expose the strong discharge channel 32. At this time, the beads falling out of the blanking box 21 can only fall into the strong discharge channel 32 and fall into the recycling box through this strong discharge channel 32. When one of the two photoelectric counters 23 reaches the preset value, the values of the two photoelectric counters 23 are reset to zero for the next round of counting. When the values of the two photoelectric counters 23 corresponding to each blanking channel 211 are the same, the third driving unit 50 drives the strong discharge blocking block 70 to rotate to cover the strong discharge channel 32, while the second driving unit 40 drives the discharge blocking block 60 to rotate to expose the discharge channel 31. In this way, by setting two photoelectric counters 23 to count the beads in a blanking channel 211, the accuracy can be greatly improved.

[0093] It should be noted that the distance between the two sets of first through holes 212 on each blanking channel 211 in the vertical direction is less than the length of a condensate bead product. In this embodiment, the distance between the two sets of first through holes 212 is less than or equal to 55 mm. This is to prevent the distance between the two sets of first through holes 212 from being too far and the condensate bead product from falling slowly, resulting in the values of the two photoelectric counters 23 always being inconsistent.

[0094] In some embodiments, please refer to Figure 13 , the second driving unit 40 includes a discharge cylinder 41, a discharge rotating shaft 42, and a discharge connecting rod 43. The discharge rotating shaft 42 is rotatably connected to a support plate 80. One end of the discharge rotating shaft 42 penetrates into the cavity of the hopper 30 and is detachably connected to the discharge stopper 60. The other end of the discharge rotating shaft 42 is fixedly connected to the discharge connecting rod 43. One end of the discharge cylinder 41 is hinged to the support plate 80, and the other end of the discharge cylinder 41 is hinged to the end of the discharge connecting rod 43 away from the discharge rotating shaft 42. When the telescopic end of the discharge cylinder 41 expands and contracts, it can drive the discharge connecting rod 43 to rotate, thereby driving the discharge rotating shaft 42 and the discharge stopper 60 to rotate, and further achieving the purpose of opening or covering the discharge channel 31.

[0095] Similarly, please refer to Figure 13 , the third driving unit 50 includes a strong exhaust cylinder 51, a strong exhaust rotating shaft 52, and a strong exhaust connecting rod 53. The strong exhaust rotating shaft 52 is rotatably connected to the support plate 80. One end of the strong exhaust rotating shaft 52 penetrates into the cavity of the hopper 30 and is fixedly connected to the strong exhaust stopper 70. The other end of the strong exhaust rotating shaft 52 is fixedly connected to the strong exhaust connecting rod 53. One end of the strong exhaust cylinder 51 is hinged to the support plate 80, and the other end of the strong exhaust cylinder 51 is hinged to the end of the strong exhaust connecting rod 53 away from the strong exhaust rotating shaft 52. When the telescopic end of the strong exhaust cylinder 51 expands and contracts, it can drive the strong exhaust connecting rod 53 to rotate, thereby driving the strong exhaust rotating shaft 52 and the strong exhaust stopper 70 to rotate, and further achieving the purpose of opening or covering the strong exhaust channel 32.

[0096] In some embodiments, please refer to Figure 2 and Figure 5 , the switch door unit 22 further includes a guide post 221 and a guide sleeve 223 installed on the mounting plate 226. The guide sleeve 223 is sleeved on the outer surface of the guide post 221 and is slidably connected to the guide post 221. One end of the guide post 221 close to the blanking channel 211 is connected to the baffle 224, and the driving source 225 is drivingly connected to the end of the guide post 221 away from the blanking channel 211. Specifically, the guide sleeve 223 is installed on the rear surface of the mounting plate 226. The mounting plate 226 is provided with a through hole penetrating through the front and rear surfaces of the mounting plate 226, and the guide post 221 sequentially passes through the guide sleeve 223 and the through hole. In the matching structure of the guide post 221 and the guide sleeve 223, it has a small friction coefficient, which can enable the baffle 224 to move forward or backward quickly.

[0097] In some embodiments, please refer toFigure 2 and Figure 5 The door opening and closing unit 22 further includes a guide wheel 227 which is rotatably connected to the mounting plate 226 and is used for rolling friction with the surface of the baffle 224. In this embodiment, the guide wheel 227 is rotatably connected to the upper end of the mounting plate 226 through a rotating shaft. By providing the guide wheel 227, the upper surface of the baffle 224 can be made to tend to be horizontal, avoiding the baffle 224 from being too skewed and causing the condensate beads to be crushed when the baffle 224 moves in cooperation with the wall surface of the blanking channel 211.

[0098] Optionally, the guide wheel 227 is a bearing, which is beneficial to improving the smoothness of the movement of the baffle 224.

[0099] In some embodiments, please refer to Figure 6 and Figure 7 The door opening and closing unit 22 further includes a connecting member 222. The driving source 225 is drivingly connected to the connecting member 222. An insertion hole 2221 for inserting the guide post 221 is provided on the end face of the connecting member 222 close to the blanking channel 211. The connecting member 222 is further provided with a card slot 2222 communicating with the insertion hole 2221. A clamping member 2211 is provided at the end of the guide post 221 away from the baffle 224. The clamping member 2211 is configured to be detachably clamped in the card slot 2222. Specifically, the insertion hole 2221 is provided on the front end face of the connecting member 222 and extends along the sliding direction of the guide post 221. The insertion hole 2221 is inserted and adapted to the rear end of the guide post 221. The front end of the connecting member 222 is cylindrical, and the card slot 2222 is provided on the outer circumferential surface of the front end of the connecting member 222. The rear end of the guide post 221 is inserted into the insertion hole 2221. When the clamping member 2211 is clamped in the card slot 2222, the guide post 221 is fixed to the connecting member 222. With such a setting, the fixing of the guide post 221 and the connecting member 222 is realized by a clamping method, greatly improving the assembly and disassembly efficiency of the guide post 221 and the connecting member 222.

[0100] In some embodiments, please refer to Figure 8 The card slot 2222 includes a first section 2223, a second section 2224 and a third section 2225 for limiting and abutting against the connecting member 222 which are connected in sequence. The first section 2223 extends along the axial direction of the insertion hole 2221 and penetrates the surface of the connecting member 222 close to the blanking channel 211. The second section 2224 extends along the circumferential direction of the insertion hole 2221. The third section 2225 extends in the direction close to the blanking channel 211 at the second section 2224. An elastic member 2226 for elastically abutting against the guide post 221 is connected to the wall surface of the insertion hole 2221 away from the blanking channel 211. The baffle 224 is rotatably clamped on the guide post 221.

[0101] Understandably, the elastic member 2226 can be a spring, an elastic column, or other elastic objects, which is not limited herein. In this embodiment, the elastic member 2226 is a spring. Please refer to Figure 6 and Figure 7 , the spring is received in the insertion hole 2221. By using fasteners 2227 such as screws or bolts, and using a pressing piece 2228 to fasten one end of the spring to the bottom wall surface of the insertion hole 2221. The first section 2223 penetrates through the front end surface of the connecting member 222 so that the engaging member 2211 can enter the first section 2223. During assembly, the guide post 221 is inserted into the insertion hole 2221 by applying force. At this time, the guide post 221 compresses the spring, and the engaging member 2211 moves within the first section 2223. Then the guide post 221 is rotated so that the engaging member 2211 moves within the second section 2224. When the engaging member 2211 moves to the end of the second section 2224, the external force is removed, and the spring resets and drives the engaging member 2211 into the third section 2225. In this way, the engaging member 2211 is clamped within the third section 2225, thereby realizing the fixation of the guide post 221 and the connecting member 222. The disassembly of the guide post 221 is also the same, which will not be elaborated here. It is worth mentioning that when the guide post 221 rotates, the baffle 224 remains in a horizontal state under the support and restriction of the guide wheel 227. The setting of the guide wheel 227 can not only reduce the damage of the condensate beads, but also ensure that after the guide post 221 is assembled to the connecting member 222, the baffle 224 can be arranged horizontally, which is beneficial to shortening the adjustment time of the baffle 224.

[0102] In some embodiments, please refer to Figure 5 and Figure 9 , a convenient structure 2213 is provided at one end of the guide post 221 close to the blanking channel 211. The convenient structure 2213 is used for driving by the staff so that the guide post 221 is detached from or fixed to the connecting member 222.

[0103] Understandably, the convenient structure 2213 can be a groove opened at the front end of the guide post 221, a boss provided on the outer circumferential surface of the front end of the guide post 221, or a protrusion provided on the front end surface of the guide post 221. As long as the staff can drive the convenient structure 2213, it is not limited herein. In this embodiment, a cross-shaped groove is opened on the front end surface of the guide post 221. The staff can drive the groove through a tool, thereby driving the rotation of the guide post 221, and further realizing the installation and disassembly of the guide post 221. When it is necessary to clean the baffle 224 or the guide post 221, the staff can directly disassemble the guide post 221 from the connecting member 222 in front of the blanking box 21. Since the baffle 224 is clamped on the guide post 221, the baffle 224 will be removed together when the guide post 221 is removed. By providing the convenient structure 2213, it greatly facilitates the staff to install and disassemble the guide post 221, thereby improving the cleaning efficiency of the guide post 221 and the baffle 224.

[0104] Of course, the shape of the groove may also be cross-shaped or other shapes.

[0105] Optionally, the rear end of the guide post 221 is indented along the radial direction of the guide post 221 to form an insertion section 2212, and the clamping member 2211 is connected to the outer circumferential surface of the insertion section 2212. The distance from the end face of the clamping member 2211 away from the axis of the guide post 221 to the axis of the guide post 221 is less than the inner diameter of the guide sleeve 223. Such a setting enables the staff to take out the guide post 221 from the guide sleeve 223 to facilitate the cleaning of the guide post 221 or the baffle 224.

[0106] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
